Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a stationary device is used for fingerprint and document recording, then recording accuracy is maintained, but passengers must exit the vehicle causing loss of time
Solution Approach 1:
The patent transforms the stationary recording device into a mobile device that can be transported to the passenger. The device includes a handheld or vehicle-mounted configuration with integrated sensors, light sources, and processing units that maintain recording precision while enabling in-vehicle operation, thus eliminating the need for passengers to exit the vehicle.
Solution Approach 2:
The mobile recording device integrates multiple functions including fingerprint sensing, document scanning, imaging, and wireless data transmission into a single portable unit. This multi-functional design allows the device to perform all recording tasks within the vehicle, saving time while maintaining accuracy through integrated sensor arrays and processing capabilities.
2Reliability
If separate devices are used for fingerprint and document recording, then device specialization is achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines fingerprint sensors, document scanners, cameras, light sources, and processing units into a single integrated mobile device. The device uses a unified placement surface with multiple sensor types that can simultaneously or sequentially capture fingerprints and documents, reducing the number of devices from two separate units to one consolidated system while maintaining the reliability of specialized sensing through integrated multi-functional modules.
3Ease of operation
If consecutive recording of fingerprints is used, then recording simplicity is maintained, but errors in association and time consumption increase
Solution Approach 1:
The mobile device captures images of all fingers simultaneously in a single placement action rather than recording them consecutively. The integrated sensor array records multiple fingerprints at once, and the processing unit automatically associates each fingerprint with its corresponding finger based on spatial positioning and image analysis, eliminating association errors while maintaining operational simplicity.
4Ease of operation
If a mobile device is used for fingerprint recording, then portability is achieved, but the ability to record multiple fingers simultaneously and documents is limited
Solution Approach 1:
The mobile device incorporates a unified placement surface with integrated fingerprint sensors, document scanners, and imaging cameras that can simultaneously or sequentially capture multiple fingerprints and documents. The device processes and manages multiple data types within a single portable unit, maintaining full versatility while achieving portability through consolidated hardware and software architecture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure, efficient, and portable identification by allowing multiple fingerprints and documents to be recorded on the same surface without the need for external power, reducing errors and increasing speed, while maintaining high-resolution image quality for database comparison.
Implementation Method 1
at least one two-dimensional or area light source by which light components of the light source can be coupled in from the direction of the sensor layer through the protective layer to the skin areas or the document to be recorded
Implementation Method 2
the at least one area light source is configured to emit light in a first angle range such that light components in the protective layer are internally reflected at the placement surface in order to record skin areas placed on the placement surface using the principle of frustrated total internal reflection
Data Source
AI summary
An arrangement and method for optical recording of live skin areas of human autopodia and documents has a layer body comprising sensor layer with light-sensitive elements in regular pixel rasters, transparent protective layer above the sensor layer as placement surface for skin areas or documents is integrated in a mobile image capture device having at least one display for user guidance and an internal power supply. The layer body has an area light-emitting layer under the sensor layer to emit light in a first angle range for frustrated total internal reflection at the placement surface when autopodia are placed thereon and to emit in a second angle range to illuminate documents on the placement surface. A controlling and data processing unit handles preprocessing and reducing captured image data and an electronic interface for wireless coupling of the image capture device with a further electronic device for image data processing.
